To determine if 2280 is a prime number or a composite number, we simply look at the factors for 2280.
If the factors of 2280 are only 2280 and 1, then we know that 2280 is a prime number. Otherwise, 2280 is a composite number.
To explain better, if 2280 is only divisible by 1 and 2280, then it is a prime number, and if 2280 is divisible by more than 2280 and 1, then it is a composite number.
The factors of 2280 are as follows:
1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 19, 20, 24, 30, 38, 40, 57, 60, 76, 95, 114, 120, 152, 190, 228, 285, 380, 456, 570, 760, 1140, 2280
Therefore, since 2280 is divisible by more than one and itself, the answer to the
question "Is 2280 prime or composite?" is highlighted in blue below.
composite
Is 2281 prime or composite?
